In a small saucepan bring cream and saffron just to a boil, and simmer until reduced to 2/3 cup, cream should thick enough to coat the back of a spoon. Cook fava beans in a saucepan of boiling, salted water for 3 minutes; drain and refresh. In a skillet heat 2 tablespoons butter, add shallot and cook over low heat just until softened. Add lobster meat and sherry, season with salt and pepper and cook over medium-high heat for 1 minute. Add saffron cream, diced vegetables and beans.
